This paper analyzes the contention that the Holocaust is unknowable, and also the notion that psychoanalytic interpretations of the Holocaust and its metaphors contrast with "aesthetic" presentations and are therefore in some way undesirable. Five possible modes of "knowing" the Holocaust are differentiated, leading to the conclusion that the Holocaust is in fact knowable, or at least subject to being known. Nevertheless, we find that the profound silences, absences, and psychospatial gaps that continue to be transmitted unconsciously across the generations tend to perpetuate certain "unknowable" aspects of the Holocaust experience. Second, the myth of the psychological unknowability of the Holocaust may mask the more profoundly disturbing theological dilemma of God's apparent relinquishing of the world to human evil. Linking concepts are provided for bridging the philosophical and clinical dimensions of the discussion.
